  • Depolymerization Technology Chemical Recycling Guide

    Depolymerization Technology Chemical Recycling Guide

    Depolymerization breaks polymers into monomers for virgin-quality recycled materials, enabling true circular economy for plastics that mechanical recycling cannot process.

    Technology Types

    Methanolysis

    For PET recycling. Produces DMT (Dimethyl Terephthalate) and EG (Ethylene Glycol). Commercially established with major players including Eastman.

    Hydrolysis

    For PA (Nylon) and PET. Water-based depolymerization at elevated temperature and pressure. Higher energy requirements but handles mixed inputs.

    Glycolysis

    For PET and polyurethane. Uses glycol to break polymer bonds. Lower severity conditions, suitable for certain waste streams.

    Enzymatic

    For PET. Uses enzymes (cutinases) to break polymer at mild temperatures. Emerging technology with commercial-scale demonstrations.

    Applications

    • Bottle-to-bottle recycling maintaining food-grade quality
    • Nylon carpet recycling to monomer feedstocks
    • Polycarbonate waste conversion to BPA

    Commercial Status

    Several commercial plants operational and under construction. Eastman, Loop Industries, and jeplan lead commercialization efforts.

    Economic Considerations

    Capital costs higher than mechanical recycling. Operating costs depend on energy prices. Virgin-quality outputs command premium pricing.

    Depolymerization essential for closing the loop on complex plastic waste streams.

    Treaty likely includes binding obligations on waste management, voluntary targets for recycled content, and financing mechanisms for developing country implementation.

    Companies should prepare for increased regulatory requirements and circular economy mandates.

  • Plastic Recycling Codes Explained Guide

    Plastic Recycling Codes Explained Guide

    Plastic resin identification codes (1-7) help consumers and recyclers identify materials for proper sorting and processing.

    Understanding Resin Codes

    The chasing arrows symbol with a number indicates resin type, not recyclability. Local programs determine actual acceptance.

    Code Categories

    • Code 1 (PET): Water bottles, food containers. Excellent recycling markets.
    • Code 2 (HDPE): Milk jugs, detergent bottles. Strong demand for recycled material.
    • Code 3 (V): PVC pipes, packaging films. Limited recycling infrastructure.
    • Code 4 (LDPE): Plastic bags, wraps. Collection programs expanding.
    • Code 5 (PP): Yogurt cups, bottle caps. Increasing recycling capacity.
    • Code 6 (PS): Disposable cups, foam packaging. Challenging markets.
    • Code 7 (Other): Mixed plastics, bioplastics. Variable recycling options.

    Recycling Reality

    Not all coded plastics are actually recycled in all areas. Recycling rates vary significantly by material type and regional infrastructure.

    Consumer Actions

    1. Check local recycling guidelines
    2. Reduce plastic usage where possible
    3. Choose recyclable materials when alternatives exist
    4. Support brands using recycled content

    Understanding codes helps make informed choices about plastic consumption and disposal.
